Product details

Overview

TEA2017AAT/2 from NXP Semiconductors is a digital configurable LLC and multimode PFC controller in SO16 package, integrating both PFC (DCM/QR/CCM multimode) and LLC control functions for resonant AC-DC power supplies. It delivers accurate primary-capacitor-voltage-based output power regulation, supports valley/zero-voltage switching, and enables <75 mW no-load input power in combination with TEA2095T - targeting high-efficiency 90–1000 W adapters and PSUs.

For engineers reviewing the TEA2017AAT/2 datasheet, TEA2017AAT/2 pinout, TEA2017AAT/2 application, or TEA2017AAT/2 equivalent, key selection considerations include programmable operation mode transitions (high-power/low-power/burst), independent configuration of OVP/OCP/OTP/OPP/CMR protections, integrated HV start-up and X-cap discharge, and GUI-driven tuning of soft-start, frequency jitter, and audible-noise suppression.

Technical Context

The TEA2017AAT/2 implements a hardware-state-machine-based digital architecture for deterministic real-time control of both PFC and LLC stages. Its V_CAP-based regulation loop directly measures output power via divided primary resonant capacitor voltage (SNSCAP), enabling precise, gain-stable mode transitions without frequency-loop instability.

PFC operation is configurable across DCM/QR, fixed-frequency CCM, or full multimode - with adaptive current shaping and PFC jitter for EMI reduction. LLC control includes valley/peak detection (DRAINPFC), capacitive-mode regulation (CMR), and burst-mode delay/exit functions to suppress audible noise while maintaining tight output regulation under dynamic load transients.

Equivalent & Alternatives

The following parts are listed as comparable options for similar digital PFC+LLC controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
UCC28070RTWR	Analog dual-phase interleaved CCM PFC only - no integrated LLC control; requires external LLC controller (e.g., UCC25630x)	Best suited for high-power (>1 kW) PFC front-ends where LLC is implemented separately; lacks V_CAP regulation and burst-mode intelligence	Select when designing modular PFC+LLC systems with independent optimization of each stage and need for phase interleaving.
ICE5QSAG	Quasi-resonant flyback + active PFC combo IC - not LLC-based; uses frequency modulation instead of V_CAP control; no low-power/burst modes	Targeted at sub-150 W applications like printers and monitors; cannot scale to >300 W or meet <75 mW no-load with same simplicity	Choose for cost-sensitive, lower-power designs where LLC topology is unnecessary and flyback suffices.

Compared with UCC28070RTWR and ICE5QSAG, the TEA2017AAT/2 uniquely integrates fully programmable multimode PFC and V_CAP-regulated LLC in one SO16 device - delivering superior light-load efficiency, fewer external components, and unified GUI-based configuration across both power stages.

FAQ

What is the primary regulation method used by the TEA2017AAT/2?

The TEA2017AAT/2 uses primary capacitor voltage (V_CAP) sensing via the SNSCAP pin as its core regulation parameter. Unlike traditional frequency-modulated LLC controllers, it directly measures output power by monitoring the difference between high and low thresholds (V_hs(SNSCAP) − V_ls(SNSCAP)), enabling stable gain and precise mode transitions. This method is implemented in the TEA2017AAT/2's digital hardware state machine and does not rely on external microcontrollers or software loops.

Does the TEA2017AAT/2 support both DCM/QR and CCM PFC operation?

Yes, the TEA2017AAT/2 supports three configurable PFC modes: DCM/QR only, fixed-frequency CCM only, and full multimode (DCM/QR/CCM). The mode is selected during configuration using NXP's GUI tool and stored in the device's MTP memory. Multimode operation allows seamless transitions between conduction modes based on line voltage and load - optimizing efficiency across the entire 90–264 VAC input range in the TEA2017AAT/2.

How does the TEA2017AAT/2 achieve <75 mW no-load input power?

The TEA2017AAT/2 achieves <75 mW no-load input power through coordinated low-power design features: V_CAP-based burst-mode control with programmable delay/exit, integrated X-cap discharge eliminating bleed resistors, HV start-up current source disabled during normal operation, and regulated SNSFB current (I_reg(SNSFB) = 80 µA) that minimizes optocoupler loading. This performance is verified in the TEA2017AAT/2 + TEA2095T reference design per the official datasheet Rev. 1.4.

Which protection features in the TEA2017AAT/2 can be independently configured?

The TEA2017AAT/2 allows independent configuration of overtemperature protection (OTP), overcurrent protection (OCP), overvoltage protection (OVP), overpower protection (OPP), capacitive mode regulation (CMR), supply undervoltage protection (UVP), and brown-in/brown-out detection. Each protection has user-programmable threshold levels, response timers, and behavior modes (latch, safe restart, or latched after retry attempts) - all stored in MTP memory and applied in real time by the TEA2017AAT/2's hardware engine.

Is the TEA2017AAT/2 pin-compatible with other NXP digital power controllers like TEA2016AAT?

No, the TEA2017AAT/2 is not pin-compatible with TEA2016AAT or other members of the TEA20xx family. Its 16-pin SO16 layout (SOT109-1) includes dedicated pins for V_CAP sensing (SNSCAP), half-bridge slope detection (HB), and dual high-voltage spacers (HVS Pins 7 & 12), which differ from earlier variants. Pin mapping, functionality, and internal architecture are unique to the TEA2017AAT/2 and require dedicated PCB layout.
